Why this matters now

• Discovery and conversion move into chat. Shoppers can ask a bot for “a mid‑range standing desk under $400 with fast shipping” and complete the purchase without visiting your site.
• Standards are emerging. Google’s Universal Commerce Protocol (UCP) and Stripe’s Agentic Commerce Protocol (ACP)/Agentic Commerce Suite (ACS) create a common language for agents, feeds, and checkout endpoints.
• First movers win shelf space. Early adopters will occupy premium surfaces inside Gemini, Copilot, Alexa.com, and device-native agents like Lenovo Qira.

Founders who move this week can capture incremental revenue and data advantage while competitors are still debating roadmaps.

What changed in the last 14 days

• Google Gemini shopping is rolling out with account-linked checkout and major retail partners, compressing discovery-to-purchase into one interface. Read announcement.
• Copilot Checkout launched on Jan 8, enabling purchases inside Microsoft Copilot with PayPal and commerce partners. See coverage.
• Stripe’s agentic standards are moving from concept to implementation via ACP/ACS and early retailer pilots. Newsroom • Spec.
• Ecosystem momentum (e.g., Mastercard trust frameworks, Lenovo Qira devices, Alexa.com web access) signals that agentic commerce is a multi‑platform wave, not a single-channel bet. Axios • Lenovo • Amazon.

The 7‑day founder plan

Day 1: Confirm eligibility and switch on what’s available

• Google: Verify your Merchant Center setup and brand profile; ensure 50+ approved offers and accurate feeds. If you have access to Business Agent and UCP‑related toggles, enable them and theme the experience (welcome copy, brand colors, support handoff).
• Microsoft: Confirm your products are indexable by Copilot (store/marketplace integrations) and request Copilot Checkout onboarding via your commerce platform or PayPal.
• Stripe: Register a sandbox, review ACP/ACS docs, and map your cart/checkout domain model to the ACP objects you’ll need for agent-driven sessions.

Day 2: Ship an agent‑ready product feed

• Enrich titles, attributes, and variant data (size, color, fit notes) and expose real‑time inventory.
• Add policy and compliance notices (materials, age warnings, battery shipping limits) so agents can answer confidently.
• Keep URLs canonical and crawlable; do not break existing SEO while adding agentic hints.

Day 3: Stand up your checkout endpoints

• Stripe ACP/ACS: Implement create/update/complete session endpoints and map taxes, shipping, discounts, and customer profiles. Start with sandbox orders and synthetic users.
• Payments and risk: Enable 3DS where relevant, configure fraud rules for agent‑initiated sessions, and whitelist agent user agents/IPs if documented by providers.

Day 4: Hardening and safety

• Ship guardrails for prompt injection and SKU swaps. Validate SKU, price, and inventory server‑side on every session change and again at completion.
• Log policy‑sensitive claims (materials, allergens, warranties) and pin each to a source of truth (schema, PDP copy, or PIM field).

Run our production‑ready checklist: Agentic Checkout Security Checklist.

Day 5: Measurement you can trust

• Tag agent surfaces with unique campaign/medium values (e.g., medium=agent, source=gemini|copilot|alexa).
• Track session primitives: agent‑initiated chat opens, product clarifications, add/remove line items, payment attempts, completions, cancels, refunds.
• Publish a simple attribution model: last‑touch within 7 days for agent orders; multi‑touch if your CRM can merge chat and web identities.

Use our playbook to define KPIs: Agentic Commerce Metrics (2026).

Day 6: Conversion content for agents

• Write short, factual answers to the top 25 pre‑purchase questions that agents ask on your category (sizing, compatibility, materials, returns, shipping cutoffs).
• Expose these answers in structured data or clearly on PDPs so agents can quote them. Keep them consistent across PDP, feed, and policy pages.
• Localize critical answers if you sell in multiple markets.

Day 7: Final QA and go‑live experiment

• Turn on a controlled percentage (e.g., 10–20%) of eligible traffic for native checkout surfaces where available.
• Run A/B on agent‑theming (welcome message, conversation starters, handoff options) and measure impact on clarification rate and checkout starts.
• Document incident response: who can pause agent checkout, roll back feed changes, or revoke credentials.

Founder FAQ

Will agent checkout cannibalize my site? Probably some, but you’ll also capture intent that would’ve bounced. Start with a capped rollout and watch blended conversion. If agents lift conversion on long‑tail queries, keep it on.

Is this only for enterprise? No. Standards like ACP/ACS are designed for broad adoption. If you’re on Shopify or a modern headless stack, you can pilot quickly.

What about privacy and compliance? Treat agent sessions like any other checkout: clear consent, auditable logs, and transparent notices. Make sure your privacy policy covers agent-to-merchant data flows and that you can furnish records on request.

Common pitfalls (and quick fixes)

• Thin PDPs → vague agent answers. Fix by adding materials, fit notes, compatibility matrices, and policy snippets to PDPs and feeds.
• Inventory drift during agent sessions. Use real‑time inventory checks and re‑validate at complete.
• Policy mismatch across channels. Keep returns/warranty text identical across site, feed, and policy pages so agents don’t contradict support.
• No incident kill switch. Assign on‑call owners and document the pause process for each surface (Gemini, Copilot, ACP endpoints).
